BUTTONNHOLE SEWING-MACHINE SPECIFICATION forming part of Letters Patent No. 298,957, dated May 20, 1884.

Application filed July 1,1882. (Model.)

T all who/'nf 'it may concer/z;

Be it known that I, FREDERICK Feen, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new andV useful Improvements in Button-Hole Attachments for Sewing-lVIachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as 1o will enable others skilled in the art to which it appertains tomake and use the same.

` My invention relates to certain new and useful improvements in button-hole sewing-machines, which may be best understood by reference to the accompanying drawings, which illustrate my machinein combination with an ordinary lVheeler di Vilson sewing-machine. Figure 1 is a vertical section of my improved machine, taken through the line e' z, Fig. 3;

` My invention is designed especially to render the operation of stitching and barring the button-hole automatic in every particular and to do away-with pawls and ratchets in connection with the feed mechanism; and with these objects in view my invention consists in the novel organization of parts and in certain combinations of devices hereinafter fully described and specifically claimed.

Ais the case,made of cast-iron or any suitable material, having an opening, B, into which fits a pin, C, arranged on the drive-bar D. This drive-bar is caused to operate by means of a pin, E, which iits into a traveler, F, in the switch-cam G2011 the shaft of the machine. The pin C, in its movement, comes in contact with a tray, D2, (shown in section at Fig. 13 and in perspective at Fig. 20,),which slides in V-shaped grooves4 a. This tray is composed of a i'lat plate, through which runs a spindle,

G, Fig. 12, provided with a disk, b, with beveled trip c projecting from its periphery. This spindle terminates in a disk, d, having also a trip, e, beveled on the under side. The plate is confined between the two disks, and over the upper disk is a standard, II, to which are pivoted on each side spring-dogsf, having beveled teeth g, Figs. 7, 8, 10, and 19. The s@ standard H rests upon the tray D2, and the disk bis free to revolve and operate on the dog f, as will be hereinafter explained, the arrangement ofthe spindle, standard, and tray being such that the sliding of the latter will carry with it the said spindle and standard. The pin C on the drive-bar D (see Fig. 13) is shown between said dogs f, so that it will be readily understood that any longitudinal movement of said drive-bar will cause the tray Dl to slide 9o accordingly, since the standard II, to which the dogs f are attached, is secured to the spindle Gr, which also passes through the said tray. If

' one of the dogs be lifted so that the pin' will be free to move underneath the same, then of 9 5 course the length of the slide (in the direction of the upraised dog) imparted to the tray. D2 will be lessened by the width of said dog. Except when the machine is performing the function of barring, one of these dogs is always roo raised by means of the trip ccoming in contact with the tooth g of the dog f, as will be more readily seen at Figs. 19 and 20, and the obj ect of this and the relation existingbetween the drive-bar and tray will be hereinafter more fully and in detail explained. The tray D2 is provided with a pin, I, secured by nut and rivet, Figs. 2, 13, and 14, which travels in a deflected or inclined slot, A2, in a jog-link, D3, (see Fig. 14,) the arrangement of this slot being such that as the tray slides the pin I will act on the jog-link and give it a motion in a plane at right angles to that of the previouslymentioned drive-bar and tray. This jog-link D3 is provided with a gating, K, into which is fitted and pivotally attached, by means of the screw h, one end of the oscillator L, so that it will be readily understood that any movement of the jog-link D3 will affect the oscillator, but in what particular manner and for what purpose I will presently explain. This oscillator L passes through an independent vibrating pocket, M, (shown in detail at Fig. 21,) which consists of a circular piece of metal, provided with a gating, N, and fitting into a -recess in aslide, O.

l? is aset-screw, by means o f which the slide can be fastened at any desired point. By

' means of the slide O the distance between it and that part of the oscillator L pivoted by the screw h is increased or lessened, thereby giving to the oscillator a less or greater vibration at its further extremity, for the purpose of causing a narrower or wider stitch of the button-hole, in the manner and for the purpose hereinafter more fully explained.

Directly upon the oscillator L is placed the feed-bar Q, provided at one end with a hookarm, R, and having two bearings, i j, the latter of which is threaded. Through these bearings 4passes a shaft, S, threaded to serve as a screw in the bearing j, and operated by a thumb-wheel, 7c. The upper end of this feedbar is provided with a pin, Z, Fig. 1, which projects from the under side of the bar, and which is designed to t into a hole in a step, m, on a slide, T, which travels in a groove in the fore part of the oscillator. The objects attained in thus practically making the feed-bar in two sections is the great convenience in the manufacture and also in assembling the several parts. To the forward and detachable end of this feed-bar is attached, in any suitable manner, any ordinary presser-foot, U, of form and style advantageous to the manufacture of button-holes, and operated by the usual cam-lever. *y Upon the feed-bar Q and pivotally attached to the case A is a clutch-vise, V. (Shown in operative position at Fig. 5 andl in detail at Fig. 9.) This vise is made with jaws n o, the latter pivoted by a screw, p, to the vise-bar, and the former bearing against a spring, g, confined by a pin, 1, and operated by a dog, s, pivoted by a screw, t, to the vise-bar. This dog is beveled at the heel end in contact with the vise, so that any rocking or vibration of said dog will cause the latter to act like a cam ywith the feed-bar when the dog s is not acting on said jaw n.

W is a at spring secured to the case A and bearing against the clutch-vise V, the object' of which is to give a spring movement to the vibrations of the vise, as will be presently explained.

X is a'short metal spring bearing upon the feed-bar Q., in order to prevent the said feedbar from slipping, and also to steady the movement of the same.

Y isa plate which is secured to the case, and having pivotally attached thereto two dogs, a v.

Attached to theA tray D2 in such amanner as to permit free vibration is a lever, A', provided with a single tooth, w, and adjusted by means of a screw, a', in the side of the case, the relations of which to the dogs u v and the clutch-vise V can be more readily comprehended by reference to Fig. 5 of the drawings. As the tray D2 moves forward, the tooth fw is forced against the dog fu, thereby crowding it in turn against the side 1 of the dog s, which, as hereinbefore explained, operates the vise and causes it to grasp the feed-bar Q, and, furthermore, by reason of the inclination of said side 1 of the dog s, the action of the dog lu thereon also causes the vise to move forward until the tooth w has passed the dog c and ceased to crowd the same. The vise immediately releases the feed-bar, owing to the normal repose ofthe dog s, and by reason ofthe spring Wdrops back to its original position. Thus it will be seen that by moving the tooth w from the position shown in Fig. 2 to vthat shown in Fig. 5 the feed-bar has been advanced, and it is clear that by a reverse movement the dog c will operate on the dog s in precisely the same way and with the same result. Therefore I will state at this point that the forward movement of the feed-bar Q is effected by the action of the dog c on the dog s, and as the functions and relations existing between the dog u and the side 2 of the dog s do not differ in the least from those already explained relative to the dog v, it follows that, the pressure in this latter case being upon the side 2 of the dog s, the backward movement of the feed-bar is effected by the action of the dog u on the dog s. The intervals in the movement of the feedbar depend entirely on the amount of pressure TOO IIO

brought to bear upon the inclined surfaces 1 and 2 of the vise, and this is rendered greater or less, according to the adjustment of the lever A', by means of the screw a.

B is a catch-lock device, by means of which motion is transmitted to the attachment, (see Fig. 22,) and consists of a piece of metal of suitable shape, terminating in or provided with a pin or trigger, C', at one end, and having a catch-tooth, b', (see Fig. 22,) at thc lower portion.

D is a fiat spring, secured at one end to the bed-plate by a screw, and with the other end fitting into the slot c', so that the device B' Vhas a spring movement vertically.

E' is a rod or arm, one end of which passes through the bed-plate, and is secured by nuts d', and the other end eXtends through the opposite side of the bed-plate, and is connected with a knob or button, F', Fig. 2, by any suitable arm, G. This rod E passes through an opening in the device B', and is curved near its center for the purpose presently explained.

H is the shaft, which has an elongated slot, c', in which plays a slide, I', which moves, in conjunction with a sliding collar, J', by means of a screw, which extends through the latter into a depression or recess in the former7 as clearly shown at Fig. 1.

K' is a spring arranged between the collar J' and the cam L', so that the former has a spring movement. Thus it will be understood that when the arm E' is moved past the tooth b' in the device I3 it will act on the collar J', thereby moving the end of the slide I' into a recess, g', in the driving-wheel M'. In this recess there is fastened in any suitable manner a lug, 7L', Figs. 1 and 3, which engages with the end of the slide I', thereby giving motion to the shaft II' as the driving-wheel M' revolves. The arm E' is bent or curved near its center, so that there shall be no lost motion between it and the collar J ',while at the. same time, the movement of the cu'rvcdor bellied portion being faster than that of the part engaging with the tooth 1)',by a well-known mechanical principle, it follows that the slide I'.

will be forced a correspondingly greater distance into the recess g', which isa result to be aimed at, since it increases the hold of the slide by presenting more surface to be acted upon by the lug 7i'. Vhen the knob F' is opA erated, the arm E' is being moved against the bevel of the tooth Z1', and causes a movement of the device B' opposite to the action of' the spring D, and it is clear that as soon as the arm has passed the tooth the spring will cause the device to drop back to its original position, and thereby lock the arm against retraction. This device B terminates in or is provided with a spindle or trigger, C', as hereinbefore set forth, which is beveled ou its end in any desired manner. This trigger extends upward through the bedplate and through the case A within the field of movement of the trip e', (seeFig. 18,) so that when said trip comes in contact with the trigger the nature of their bevels will cause the trigger to be pressed downward, and thus release the arm E', for the purpose hereinafter fully explained. Thus it will be observed that the movement of the arm E' is the prime auxiliary to the applioperation will cause the action of the same to be immediately suspended by reason of the withdrawal of the slide or arm I' from contact with the lug 7L'.

In the spindle G, Figs. 12 and 18, is a pin, i', which projects on each side so as to afford a grasp or foot-hold for a toothed wheel, N', which is placed in position over the spindle, as shown 'at Figs. 2 and 20, so that any rotation of the wheel would cause a similar rotation of the spindle and the parts attached thereto.

O' is a cap, which is placed over the standard H, said cap having an elongated opening through which the spindle G projects, Fig. 20. Attached to this cap are two pawls, j', Vwhose movement is of a spring character by reason of springs k' at their rear ends. When the feed-bar Q is moved forward by the action of the vise V, its hook end R comes in contact with the trip e, Fig. 1S, and carries the same along with it until the wheel N' has been rotated sufficiently far so that the first tooth thereof, which I have designated by the letter z', strikes the pawl j', as seen at Fig. 20, during the sliding movement of said wheel through the cap O'. This causes the wheel to revolve, and the action of said pawl on said tooth brings the teeth z2 and z3 successively within the field or reach of the pawl, so that they are similarly rotated. The trip e has been thus carried around to the position as seen by dotted lines, Fig. 18, and, as will be presently explained in detail, the motion of the feed-bar is' now reversed. and the arm S acts on the trip c in precisely the same manner as the hook end R, and the contact of the teeth with the other pawl, j', opposite to that above mentioned, operates to revolve the wheel N', as previously set forth, and that after the third tooth, c, has been turned by the pawl, the trip c, in its rotation, comes in contact with the trigger C' and stops the motion of the attachment, as hereinbefore set forth. In order to more clearly illustrate my improvement, I will proceed to describe the operation of the same and the peculiarities and application of the various parts, as best seen from a practical stand-point. j

The machine is set in motion by the lug h' coming in contact with the slide I', which slide is operated by moving the knob orbutton F' by hand toward thedriving-whcel, the details of' which operation and the construction of the several parts having been already fully eX- plained. As the shaft revolves the action of the traveler F in the switch-cam G2 causes the Ioo IIO

IZO

drive-bar D' to move in aline parallel to the other words, a motion at right angles to that of the previously-mentioned drive-bar and tray, whereby the oscillator L, connected to said jog-link, is vibrated for the obvious purpose of shifting the cloth or other material underneath the needle.

In order to perform its functions properly and uniformly, the machine at its initial movement is in about the position shown at Fig. 19. By reference to this figure it will be seen that the trip c is in a position under the tooth g of the pivoted dog f, so that the latter is raised, and the pin C, Fig. 13, in its movement forward,wil1 pass underneath the dog f without coming in contact with it. This of course shortens the slide of the tray D2 by a distance equal to the width of the raised dog, so that as long as the position of the trip c and dog j is as shown at Fig. 19 the lever A, Figs/2 and 5, will move to and fro only about half of its sliding limit, and the tooth w will consequently operate on the rear dog, o, thereby causing the feed-bar Q to move forward during both the forward and backward slidev of the tray D2, as hereinbefore set forth. During the process of this operation, while the feedbar is constantly advancing, the hook R comes in contact with the trip e, Fig. 18, and forces it along with it until it has carried the trip c from under the tooth g,when the dog f drops, and the position of the pin C being now immediately between the two dogs f, there will be no lost motion, but the tray D? will slide to its full extent, causing the-leverA to operate through the medium of its tooth w upon both of the dogs u o, thereby effecting a neutralization of the feed movements, so that the bar Q will move forward and backward at each slide of the tray Dwhile at the Sametime, the tooth z of the wheel N having been brought into a position so as to strike the recess in the pawl j', each backward slide of the said tray will cause the rotation of the wheel in the manner hereinbefore set forth until it has carried the trip c around underneath the tooth of the rear pivoted dog, f, at which time the tray D2 has advanced to its fullest extent, so that, as before, said slide will move only one-half of its limit; but in this latter case the tooth w will operate on the forward dog, u, thereby causing the backward movement of the feed-bar Q, as hereinbefore set forth.

It will be readily understood by reference to Fig. 18 that, the trip e having been carried around by the revolutionof the wheel N to Y the position as indicated in dotted lines, the

arm or shaft S, during the backward movement of the feed-bar, will operate precisely as did the hook R during the forward movement, and the functions of the wheel N and the action of the opposite pawl, j', will be precisely the same, and will have the same result,with the exception that the trip e, during "its revolution, strikes the beveled trigger C and causes the attachment or machine to stop running. This trigger, however, is situated at such a point in the arc of revolution of the trip Ve that no necessary movement of themachine is lost, Aand said trip, at the end of each revolution, has consequently brought the trip c to the position from which it started-viz., underneath the tooth g of the forward pivoted dog, f-so that when the machine is again set in motion the shaft will have the same number of revolutions, and therefore the work of finishing button-holes will be uniform and complete. f The feed-bar Q is regulated in its movement by the screw a', Fig. 5, as the dogs u@ are thereby caused to crowd the beveled nose of the vise-bar V more or less, thus forcing the latter forward or backward, as the case maybe, a greater or shorter distance, for the purpose of varying the distance between the stitches of the button-hole. As hereinbefore explained, the vibration of the oscillator L is regulated by the slide O, upon the adjustment of which depends the width of the stitch. The scope of the vibration of the oscillator is doubled at the barring operation, because the slide ofthe jog-link D, to which the oscillator is attached, is twice as great at this time, owing to the increase of the slide of the tray D2, as hereinbefore set forth. The length of the button-hole is governed by the action of the feed-bar Q and its arm S, for, if a shorter button-hole be desirable, the operator merely pushes the'feed-bar forward until the distance between the needle-hole in the.

bed-plate of the machine and the rear end of the presser-foot proper is equal to the required length of the button-hole. The hook-arm R will then be in aposition to act sooner upon the trip e, and the arm S must likewise be ad- -justed inward by means of the thumb-wheel 7c. For the sake of convenience" and accuracy, graduated scales may be marked off on the slide T and bar S.

P is an auxiliary presser-foot, pivoted at Z and operated by the mechanism illustrated at Fig. 6, in which I have shown a wheel, Q, having a piece, m', secured thereon, so that a portion ofthe periphery of said wheel will be raised in order to operate upon the pivoted arm R', the upper end of which is in contact with a pin, fn', on the rear end ofthe presserf foot P. A spring, o', bears upon the pin n', as seen at Fig. 14, by reason of which the presser-foot iiies back as soon as the raised surface m has ceased to operate on the pivoted arm R. This piece mis so arranged as regards the timing of the machine that it causes the forward end of the presser-foot P to de- IOO IIO

scend and bindthe cloth j ust before the needle' -V pun ctures the same, and it remains in this position until the needle has been withdrawn. The object of this is Yto prevent the cloth from cockling, and thereby distorting the buttonhole. treme forward end of this presser-foot P, in which a knife or cutter of any desired shape can be placed, so as to cut the button-hole during the process of stitching; but I prefer to cut it in the usual manner after it is made. Should an increasedV number of barring-stitches be- I have shown a small slot in the ex! come desirable, this can be effected by an additional number of teeth on the wheel N', and at the same time the length of the teeth is shortened, so that the revolution of the wheel will be less at each action of the spring-pawls.

I have shown and described mechanism for limiting the number of oscillations and automatically stopping the machine, and also means for throwing the machine in and out of connection with the driving-wheel; but I do not wish to be understood as claiming herein any such construction, broadly, as I have claimed the latter 'in my pending application for Letters Patent, No. 98,950, Serial, iiled June 22, 1883.
